Normal Operation and Fault Conditions
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The RCM monitors the driver door side impact sensor, second row right side impact sensor, third row left side impact sensor and the circuits for each sensor for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted driver door side impact sensor
- Faulted second row right side impact sensor
- Faulted third row left side impact sensor
NOTE:
A short to ground on either impact sensor feed circuit sets DTC B1414:11, B1416:11 and B1419:11. A short to voltage on either impact sensor feed or return circuit sets DTC B1414:93, B1416:93 and B1419:93.
If a fault is detected, the RCM stores DTC B1414:11, B1414:93, B1416:11, B1416:93, B1419:11 or B1419:93 in memory and sends a message to the IPC to illuminate the airbag warning indicator.
The RCM communicates with each impact sensor. If the RCM is unable to communicate with the sensor, a DTC is stored in memory. A Continuous Memory Diagnostic Trouble Code (CMDTC) no operation (failure type: 93) can be set due to a short to voltage on the return circuit of the impact sensor.
